That is, when a person changes his job and residence, he can transfer the original social security relationship to the new job and residence at one time, or transfer the new social security relationship to other areas again. So social security can be transferred twice at most.

It should be noted that social security transfer needs to meet certain conditions and procedures, and the specific transfer regulations and procedures may be different due to different regions and policies. Generally speaking, individuals need to go through the social security transfer procedures in their new jobs and residences, provide relevant materials and apply for them, and wait for the approval and handling of the social security department.

Social security is handled as follows:

1, go to the local social security bureau. Locals who need to buy social security can go directly to the local local tax bureau to buy it;

2. Personal affiliated units handle social security and purchase in the name of human resources companies. Individuals sign agency contracts with human resources agency companies, submit relevant materials, and pay social security fees and service fees;

3. At present, in order to make citizens enjoy more convenient services in the process of handling social security, some regions have launched personal social security services online. Before opening online social security services, individuals must apply to the local tax authorities for their online passwords with their ID cards, and then they can open them at any time.

To sum up, it is recommended that individuals carefully understand the local social security policies and transfer regulations before handling social security transfer to ensure that their social security rights and interests are guaranteed.
